The PCs co-operating into the Distributed Measurement System (DMS) can work on synchronized modality on the basis of the standard IEEE 1588. Nevertheless, the hardware and software architecture of the path involved in the communication PC-Measurement Instrument (MI) can delay the command. The research given in the paper aims to investigate about the time delay introduced by the software in the communication between the PC and the MI, by referring to the previous established hardware connection PC-MI offering the minimum delay. The analyzed solution concerns with the modification of the Linux software driver of the WiFi receiver so as to make fast the software processing of the message received at the interface PC-DMS and transmitted to the interface PC-MI. This solution is compared with another two solutions based on particular setting up of non predictive software Linux OS, and employment of Linux OS RT.
